E L EVATO R Y, SPECIFICATION forming part of Letters Patent No. 268,623, dated December 5, 1882,

` Application mec May 8,1882. (No model.)

To all whom tt may concern `Be it known that we, OSCAR H. CHILD and LARGE M. COLLINS, both of Boston, in the' county of Suffolk and State ot' Massachusetts,

have invented jointly new and useful Improvements in Elevators, of which the Afollowing, taken in connection with the accompanying drawings, is a specification.

Our invention relates to self-closing doorways and hatchways for elevators; and it consists, first, in the combination, with the elevator-well and a car arranged to move vertically therein through two or more stories of a building, of a exible apron connected by one end to the car and at its other end to the top or betteln ofthe well, and adapted to move with the carin such a way that, in whatever position the car may be, all of the doorways or open'- ings to the well, except the one opposite which the car may be, will be so closed or guarded that it would be impossible for a person to fall into the well. A

It further consists in the combination, with an elevator-well and a car arranged to move vertically therein, of two liexible aprons arranged upon opposite sides ot' the well, and each attached by one'end to the car and at the other1 endto the top or bottom ofthe walls of the well, and one or more hatch-covers attached to said aprons or guards and adapted to be moved up and down as thecar is moved, and to close the openings through the oors when in their normal position.

Figure 1 of the drawings is a vertical section ou line x a: on Figs. 2 and 3. Fig. 2 is a horizontal section on line y y on Fig. l. Fig. 3 is a horizontal section lon line z aou Fig. l. Fig. 4 is a vertical section on line w w on Fig. 1, looking toward the left hand. Fig. 5 is a similar section on line u u on Fig. l, looking toward the right hand, and Fig. 6 is a vertical section illustrating a modification of our invention, in which entrances are arranged upon two sides of the well and hatch-covers are applied below as well as above the car.

A A are four posts, extending from the bottom ot the basement up through the floors B, C, D, and E, and to a point some distance above the upper iioorfE, and forming the corners of the elevator-well.

F F are two posts, arranged centrally between two of the posts A, upon opposite sides of the well, and each provided with the inwardly-projecting rib or lip a, which serves as a guide for the car in a well-known manner.

G is the car, suspended by the wire rope b from the pulley H in a WelLknown manner.

I I are flexible aprons, composed in the case illustrated of a series of slats or bars, c c, eX- tending horizontally across one side of the well, and arranged to be moved up and down in grooves d d formed in the postsA A, and connected together by means ofthe exible bands or chains e e, in such a manner that when said bands or chains are extended the barsv c c will be about an equal distance apart, as shown in the lower parts of Figs. l and 6. One end ot' each ot' the'bands or chains c c is made fast to the car G, and the other end is secured to some fixed part ot' the framing of the building, either at the top or bottom of the well, according as to whether it is above or below the car.

ln Fig. 1 the opening J, which opens to the well from the sidewalk f, is closed, when the car moves up, by the short apron I', composed ot' the bars c c, secured to the straps or chains c e', and moved upward .automatically by the weights g g, acting through the cords h It and pulleys 'i t', as shown in Figs. l and 5.

L L are hatchway-covers secured to, held in suspension by, and adapted to be moved up and down withthe exhle aprons I I, all so arranged that when said aprons are extended a hatchway-cover, L, shall close an opening in each oor below the car when it is at the top of the well, or above it when it is at -the bottom ofthe well, as illustrated in the lower part ot Fig. 6.

As the car G is moved upward it comes in contact with the first pair of bars, cc, above it, when they are carried upward with the car till they come in contact with the second pair ot bars, c c, and they are moved upward, and so on till all the bars c c that are above the car are packed close together, as shown in Figs. l, 4, 5, and 6. At the same time the hatch-covers L that are above the car are carried upward and occupy the position shown in Figs. l and 6, and the bars c c and the hatchway-covers that are ,below the car are moved into the positions shown in Fig. 6. If the car be now moved down ward,the aprons below the car will be col- IOO sa cesena lapsed, and the bars c c and covers L willbe packed together in the basement below the lower opening, while the exible guards I I above thev car will be extended and the covers 'L will be brought into the proper positions to close the openings in the floors D andE. In case of the arrangement shown in Fig. l, when the car descends to a position with its platform on alevel with the sidewalkfthe bars c care all moved down by the car into the basement, the weights g g being raised to permit such downward movement, and when the car is moved upward again the weights g g descend again and cause the bars c c to rise to the position shown in Fig. 1.

Instead ofthe bars c c and bands or chains e e, a flexible apron of cloth or netting may be used, if desired; but we prefer the bars and bands or'chains, as shown.

With our device properly applied' to an elevator-car all danger of accidents from persons falling down the well will be obviated, as no opening to the well through which a person could fall will be ungnarded at any time, except the one opposite to which the car is standing or passing.

What we clai-m as new, and desirev to secure byLetters Patent of the United States, is-

1. Incombination with an elevator-well and a car arranged to move vertically therein, a 3 flexible apron connected at one end to the car and at the other end to a fixed portion of the framing at the top or bottom of the well, substantially as and for the purposes described.

2. The combination of an elevator-well, acar 3 arranged to be moved vertically therein, iiexible aprons arranged upon opposite sides of the well, and each attached by one end to the car and at the other end to some fixed portion ofv OSCAR H.
